52 \item[ $ C \hasparents \set X $ ]
53 The parents of commit $C$ are exactly the set
57 $C$ is a descendant of $D$ in the git commit
58 graph. This is a partial order, namely the transitive closure of
59 $ D \in \set X $ where $ C \hasparents \set X $.
62 Informally, the tree at commit $C$ contains the change
63 made in commit $D$. Does not take account of deliberate reversions by
64 the user or in non-Topbloke-controlled branches; these are considered
65 normal, forward, commits. For merges and Topbloke-generated
66 anticommits, the ``change made'' is only to be thought of as any
67 conflict resolution. This is not a partial order because it is not
74 No replay: \[ C \has D \implies C \ge D \]
76 Unique base: \[ \mathop{\forall}_{C \in \py} \pends{C}{\pn} = \{ B \} \]
